Hey guys!
The wordbound blanks project handles blanks that are supposed to be
reordered. Therefore, we no longer need the user to be worried about blank
positions in transfer rules. The latest update to the apertium code makes
it such that <b pos="X"/> is now the same as <b/> . You can change the <b
pos="X"/> in your transfer rules to just <b/> and it'll work.
Now, the only thing you need to worry about when writing transfer rules is
whether you want a blank between the two LUs or not. *Input blanks will be
stored as a queue and will be printed in order in all available <b/> spots
in the rule output. *
*Note:*
- If the output rule has more blank spots than input blanks, then the
remaining blank spots will be spaces.
- If the output rule has less blank spots than input blanks, then the
remaining input blanks will be output after the rule output.
- If the input blank is an empty string, it is stored as a space.
In some transfer rules, there are input patterns which don't have a space
between them. In the output section of these transfer rules, <b pos="1"/> used
to give an empty string, but it will now give a space. To remove the blank
from the output, you will need to remove the <b pos="1"/> from the transfer
rule and it will be fine.
Here are some examples from the tests.
EXAMPLE 1:
Input:
[blank1] ^worda<det>/wordta<det>$ ;[blank2]; ^wordb<adj>/wordtb<adj>$
[blank3]; ^hun<n><acr>/ho<n><acr>$ [blank4]
There's no <b/> in rule output, so all blanks are after flushed after rule
output.
Output:
[blank1] ^test1<adj>{^wordta<det>$^wordtb<adj>$^ho<n><acr>$}$
;[blank2]; [blank3]; [blank4]
EXAMPLE 2:
Input:
[blank1] ^wordb<adj>/wordtb<adj>$ ;[blank2]; ^worda<det>/wordta<det>$
[blank3]; ^hun<n><acr>/ho<n><acr>$ [blank4]
There's one <b/> in rule output, so it prints one and flushes the rest.
Output:
[blank1] ^test1<det>{^wordta<det>$ ;[blank2]; ^ho<n><acr>$}$ [blank3];
[blank4]
This has been implemented for the chunker, interchunk, and postchunk.
If you have any questions, suggestions, comments, etc., I'll be happy to
respond to them.
Thanks and Regards,
